Application filed Hoven/ib er To all io/0m may concern.'

le it known that l, Bor E. VAN lioosnan, a citizen of the `United States, residing at lliillsdale, in the county of Hillsdale and State of liiichigan, have invented a new and useful Switch, of which the following is a specification.

This invention relates to moulding machimes, and more particularly to a novel form of electrically controlled means for `in'iparting vibratory movements to the pat tern supported by the movable arm.

rthe primary object of the invention is to provide a means of this character, to eliminate any possibility of destroying the. mould when the pattern is removed therefrom.

A further object of the invention is to accomplish the foregoing resultby preventing the adhering of the sand to the pattern.

WT ith the foregoing and other' objects in view which will appear as the description proceeds, t-he invent-ion resides in the combination and arrangement of parts and in the details of construction herein described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed7 Without departing from the spirit of the invention.

Referring to the drawings Figure 1 illustrates a side elevational vieiv of a moulding machine, showing the electrical vibrator applied thereto.

Figure 2 illustrates a sectional view through a switch employed in connection with the vibrator. f

Figure 3 illustrates a transverse sectional view through the same. y

Referring to the drawings in detail, the moulding machine is of the usual construction, and includes the base 5 supported on the Wheels 6,v there being an arm 7 forme-d integral with the base, on which arm Z isv pivotally supported the arm 8 which in turn supports the mould proper, indicated by the reference character Forming a part of the moulding machine, is the usual rock arm 10 which has pivotal connection with the arm 7 to permit the same to move a pattern, not shown, onto the mould 9.

A vibrator of an electrical type, is supported on the arm 10, the same being indicated by the reference character 11 so that i, ieee.y serial ne. raam-c.

operation of the vibrator' 11 causes a; relative movement ofk the arm 10 to cause the sand to loosen fromthe pattern.

The switch member illustrated at 12 forms an important feature of the invention and includes a housing having removable end `Walls 13 and 14, which have bearings 15 in which operate the shaft 16 that carries the movable contact disks 1?.J rlhese disks 17 have a portion' of the peripheries thereof formed of suitable conductive material 18 so that every revolution of the disks 1'7 brings the conductive material into contact with the stationary switch members 19 and 20 to complete a circuit to the vibrator 11.

It is of course understood that the post tioning of the dislrs 17 on their supporting shaft is such that the conductive material will cont-act with the stationary Contact members 19 at predetermined intervals, or when the arm 1u is in a position to release the mould.

rlhe shaft 1G is of a hollow construction to permit the Wires 2O to pass therethrough, where the same have connection with the conductive material 18 as through the securing` members Q1. Une extremity of the shaft 16 is threaded as at 22 so that the same may be threaded into one end lof the shaft 23,' which is connected with the arm 10 to move therewith, thereby automatically operating the switch members by the movements of the arm 10.

ln the operation of the device it is obvious that as the arm 10 moves in the usual manner, movement is imparted to the switch member to cause a circuit to be completed through the wires 24: to the vibra-tor 11 positioned on the arm 10, causing a vibration on pattern fastened to arm 10 While 4mould 9 is being droppeddown avvay from pattern.

Having thus described the invention, What is claimed as new is 1. In a mouldingmachine, a frame, a mould support forming a part of the frame, a movable arm mounted above the mould support, said movable arm adapted to support a patterm` a switch member including stationary contact members, and a pair of movable contact members, means for conH neet-ing the movable contact members and the pattern supporting arm, a vibrator carried by the pattern supporting arme, and said movable contact members adapted to engage the stationary Contact members to complete a cirout to the vibrator to move the pattern supporting arm.

2. In a moulding machine, a frame, a mould support forming a part of the frame, a pivoted pattern supporting arm operating above the mould7 a shaft on Which the pvoted arm is mounted, a vibrator `carried by thel pvoted arm, a switch member ineludng stationary Contact points and movable Contact points, said stationary Contact points being n circuit with the vibrator, a shaft for supporting the movable Contact points, means for connecting the last mentioned shaft and shaft supporting the pvoted arm, whereby movement of the pvoted arm moves the switch members to complete a circuit to the vibrator and cause the pvoted arm to move.

In testimony that I claim the foregoing as my own, l have hereto axed my signature in the presence of two Witnesses.
